Polytechnic

Sorry, you can't do it as it requires 10+2 but you can apply for lateral entry in best college like MIT or government college without doing JEE Mains in B.Tech. it's an easier way but you can not appear for IIT.

It completely depends on your interest. If you want to gain more valuable degree, then wait 1 year, prepare yourself and get admission in a good college or you can go for polytechnic and after completion of 3 years, you can directly get into B.Tech.

Diploma is the education course of duration ranging from 1 to 3 year. Diploma can be done in any specialized subject. Colleges which provide diploma course in engineering field are called as polytechnic college.

Both of them are good, but I will suggest you to go for interior designing.
1. It is a very creative field.
2. People you'll meet will be very imaginative and creative.
3. Competition is also less.
4. You can get higher wages but not in India.

You should pursue polytech in architecture. Instead of this, it is better to go for polytechnic in civil.

I think a place doesn't matter for education.
The things that matter are all about colleges like its facilities, faculty, placement and other such factors.

Hello Sandy,
Definitely she can pursue her Bachelors from India. For that she has to apply to the universities and then apply for study permit in India. Once the study permit is issued, she will be eligible to study here. And one more thing, fees will be pretty high for international students.
All the best.

It has a good value and you can get entry level jobs through it. You may either opt for B.Tech through lateral entry or continue working and opt for engineering through distance education.
